The Movie Quality Icon

Changes to settings are reflected in the n movie quality icon as shown. Up to three combinations can be saved.

  1. Movie Resolution
  2. Playback Frame Rate
  3. Motion Compensation

Movie Resolution

4 4K 3840 × 2160
3 FHD (Full HD) 1920 × 1080
5 C4K (4K Digital Cinema) 4096 × 2160

Motion Compensation

I-8 1 A-I (ALL-Intra2)
L-8 1 L-GOP (LongGOP)

When [nVideo Codec] is
[H.264]: “-8”
[H.265]: “-10”

When ALL-Intra is used, the movie will be recorded without interframe compression. It is suitable for editing, but the data will be large.

  • Fixed to [L-GOP] when [Movie Resolution] is [4K] or [C4K].

Playback Frame Rate

60p 59.94p (59.94fps)
50p 50.00p (50.00fps)
30p 29.97p (29.97fps)
25p 25.00p (25.00fps)
24.00p 24.00p (24.00fps)
24p 23.98p (23.98fps)
  • [24.00p] can only be selected when [Movie Resolution] is [C4K].

Slow or Fast Motion

Off
Number (rate)
  • Large rate means fast recording and small rate means slow recording.
  • Because the movies are played back at the designated speed, they will look like slow motion/fast motion movies.
  • Sound is not recorded.
  • Art filters selected in Picture Mode are disabled.
  • Slow recording and/or fast recording may be unavailable depending on the [nX] setting.
  • Only 1/24 or higher shutter speed is available. Availability depends on the [Frame Rate] setting.
  • Depending on the card used, recording may end before the maximum length is reached.
  • Motion Compensation selection may be unavailable at some settings.
  • Movies are recorded at an aspect ratio of 16:9. C4K movies are recorded at an aspect ratio of 17:9.

Filming High-Speed Movies

Film at high frame rates. Movies are filmed at 100 – 240 fps and play back at 23.98 – 59.94 fps. Stretching playback to 2× – 10× the recording time lets you view in slow motion movements that in real life took only the blink of an eye.

A high-speed movie option can be included in the movie image quality menu. Your choice of playback frame rate determines the playback speed multiplier. Limitations apply to combination of the Sensor Frame Rate and Playback Frame Rate.
